- Pressure- & media-resistant options for potable and wastewater lines
- Compatible with common receivers/locators
- Multiple diameters & designs—from service lines to trunk mains
- Expert support & consulting by SEMPERDEAL
What is a locating sonde?
Locating sondes (also called probe or sewer sondes) are battery-powered transmitters that emit a defined signal. With a compatible receiver you can determine the position and depth of the pipe or an obstacle—ideal for documentation, maintenance and damage assessment.
Potable vs. sewer: choosing the right sonde
Potable water sondes feature pressure-rated, corrosion-resistant housings for clean media and water supply networks. Sewer sondes are built for abrasion and contamination, and can be pushed through building drains, service laterals and trunk sewers using push rods or inspection systems.
Frequencies & range
Lower frequencies (e.g., 512/640 Hz) offer pinpoint accuracy at greater depths with low susceptibility to interference, while 33 kHz is a versatile standard with strong signal pickup. Match the frequency to the environment, depth and pipe material.
Selection guide
- Pipe diameter & medium: choose the proper sonde size and sealing
- Depth: align range/frequency with expected depth and surroundings
- Compatibility: ensure frequency matches your receiver/locator
- Handling: mount on push rod, inspection cable or push stick
Typical applications
- Determine pipe routes & find branches
- Pinpoint blockages and obstructions
- Depth measurement & route documentation
FAQ
- Which frequency should I use?
- For deeper placements and low-interference locating, use 512/640 Hz; 33 kHz is a universal standard for many scenarios.
- Will the sonde work with my receiver?
- Yes, if the frequencies match. Check the technical data of both sonde and receiver for identical bands.
- How do I choose the optimal sonde size?
- Base it on pipe diameter and bend radii. Smaller sondes pass bends more easily; larger sondes are easier to detect from greater depth.
- Are sondes suitable for pressure pipes?
- Pressure- and media-resistant versions are available. Observe the specified pressure rating and sealing class.
- How is the sonde inserted?
- Using push rods, inspection systems or cables. Secure the sonde and guide it gently through bends and fittings—never force it.
